You Won't Believe Which Disney Channel Stars Are Coming Back With New Music

It’s the ultimate blast from the past.

Between Disney bringing back all of your favorite original movies and the High School Musical 4 movie (which you can still audition for), nostalgia continues to win this year. And if that wasn't enough for you, here's one more blast from the past: Yesterday, the ultimate sister duo blew our minds by dropping major news about their new music. Any guesses on who it could be?

Aly Michalka posted a picture on Instagram with her sister AJ confirming that they're back in the studio! Even though they weren't photographed in a recording booth or with any instruments, the picture does show the duo in an empty auditorium. Hopefully that's a sign that the girls are already scouting a venue for their next show.

From "Chemicals React" to "Potential Breakup Song," their music library is full of throwback classics that OG Disney kids still know by heart. And in honor of this incredible news, celebrate the moment by revisiting one of their old music videos. You know you want to.
